A method to add validation in xml configuration file

Abstract

The invention discloses a check adding method into an XML configuration file. The method includes adding a check element into an original XML configuration file to obtain a new XML configuration file; replacing the original XML configuration file with the new XML configuration file with the check element; and checking the new XML configuration file before use, reading the check element information in the new XML configuration file, recomputing a checksum of the new XML configuration file, comparing the computed check with the read check information to check whether the two are in accordance so as to guarantee the correctness of the XML configuration file. According to the method, the original XML configuration file structure cannot be destroyed through adding the check element into the XML configuration file, program running is not affected, accident file modification can be discovered timely, illegal XML configuration files can be prevented from beings used, and the reliability of the system can be improved.

Description

technical field [0001] The present invention relates to a method for verifying XML (eXended Mark Language, Extensible Markup Language) configuration files, in particular to a method for adding verification to XML configuration files, especially CRC (Cyclic Redundancy Check, Cyclic Redundancy Check) ) method of verification. Background technique [0002] The XML language is Extensible Markup Language (Extensible Markup Language), which is a common markup language, similar to HTML. The XML language is mainly used to mark electronic documents to make them structural markup languages. It can be used to mark data and define data types. It is a source language that allows users to define their own markup languages. An element is the most basic unit of XML, which consists of start tags, attributes and end tags. For example: <elementName att1Name="att1Value"> is an example of an element. Each element must have an element name, and an element can have several attributes and ...

AI Technical Summary

Problems solved by technology

[0007] At present, there is no method for checking the integrity of XML configuration files, and it is relatively simple to judge whether the file format is correct, and it cannot ensure that the file content is correct.

For example: modifying the element attribute value in the XML file at will will not change the file structure. In this case, the result of judging the file format is still correct, so the reliability of this method is not high, and the XML configuration file cannot be guaranteed. correctness and usability
